1 Technical Information TI 024 N/08/en/10.05 Inteligent Digital Transmitter TMD Series Digital transmitter for float type level gauge Introduction The TMD series is a 2-way 2-wire transmitter with built-in microprocessor, used in combination with field level gauges, e.g. LT series. It enables remote calibration of tanks. Information between the transmitter and receiver are selected from variety of input/output modules to meet various specifications. With the module card technology, module can be easily changed, added and combined according to particular requirement. Features Calibration and adjustment for transmission output can be done by HHT (handheld terminal) with a fiber optic cable after the installation of the transmitter (the HHT is also used for other TMD transmitters) TMD series is a compact design and weighs only 10 kgf. Modules for remote transmission output, temperature A/D conversion, level alarm and output for external instruments operation, etc., are available, enabling application to various specifications It can be connected to existing or newly-mounted tank gauges of ours just by installing the modules The main body with EX-protected construction (JIS d 2 G 4 ) is also available and can be used in hazardous areas Specification Level A/D conversion: Optical non-contact absolute encoder Range: 0 ~ mm Accuracy: ±1 mm Power supply: AC100V, 110V, 200V, 220V, ±10% 50/60 Hz

2 Specification (cont.) Power consumption: Approx. 7VA, max, 22VA (2-way 2-wire level transmission) Ambient temperature: -20 ~ +60 C Lightning arrester: Equipped as standard Protection: Weatherproof (IP 55) Flameproof (d 2 G 4 TIIS) - threaded steel conduit type (EEx deiibt6/ ESi) - packing joint type Weight: Approx. 10 kgf Material: Main body, AC4C Body color: Silver (standard) Installation: Mounting on the rear side of tank gauge e.g. LT series (with some adapter installation on other manufacturer s level gauge is possible) TMD transmitter receives liquid level data and all following data, then transmits them to receiver by digital pulse signals (2-wire transmission boards PDC-1 and TRC-1 are necessary. Temperature signals are also available with 4~20 ma) Operation Principle The amount of wire and tape movement of the mechanical level gauge corresponds to liquid level in tanks. The movement is transmitted to measuring drum, which turns the coupling of the level gauge, and is further transmitted to the transmitter. In the transmitter, the level changes transmitted via the TMD TRANSMITTER coupling, gear unit and timing band to the level encode are converted to digital level values. The level values are computed and diagnosed by microprocessor. It processes output alarms and controls temperature element at the same time accordingly. The temperature data are also output with digital or analogue signals.

External Instrument Operation Output CNT-2 Signal: Relay contact Operation function: Operation command is given from Sakura Endress receiver to relay and then the relay starts to operate the external instruments. Contact point: 8 points Cable: Contact capacitance: 16-core (8 points) 220V DC/250V AC max. 2A Patented 2-way 2-wire link transmission system 2-way, 2-wire link transmission has been developed by ourselves in the consideration of avoiding incapability of whole loop data collection caused by loosen or severed line connection. This allows almost no data collection failure like serial connection method by employing serial transmission setup in tank yard under several ambient conditions.
